13 Question IQ Test

This 13 question untimed test is designed to measure your general intelligence.

Please do not use any reference materials (e.g. books, calculators, online or computer resources) or the help of anyone else in working these problems. You may use scrap paper, and pen or pencil.

Many of the problems are quite difficult, and some may contain words, names or terms with which you are unfamiliar. Be sure to answer every problem, even if this means guessing on some problems. There are no penalties for guessing.

Although there is no time limit, try to complete the test in 1 or 2 sessions.

Your estimated IQ score, general population percentile ranking, and the answers to the problems are all provided when you complete the test.
